Well, I had to supply a number of documents, including drivers licence details, passport of course, vehicle registration papers, photos of the bike front back and both sides.
Once they issued me with an LOI I was able to process my Chinese Visa
Once I entered the country they issued me with temporary drivers licence and temporary rego plates
Our group was never at any stage given access to the documents that were then filed on our behalf to the Chinese authorities.
That is why it is a monopoly, we as outsiders do not get to see the paperwork process that goes on behind the scenes
I know you will NOT be able to travel without a guide, the guide does not drive so you must supply him/her with transport, either by hiring a driver or placing him/her in a vehicle travelling with you, this is what we did.
Good luck trying to beat the system, their inscrutable pockets are lined and even after we ticked all the boxes and jumped through all the hoops, we still had issues with them.
